Metal jewelry production process

The production process of metal jewelry usually includes multiple delicate steps, from design to finished product storage, each link is crucial. The following is a typical metal jewelry making process:

First, the design phase

Design idea: Designers draw sketches of new works on paper and use pencils, gouache and other tools to complete the design sketch. This process can last anywhere from a few days to a few months until the design is finalized.

Mold making: According to the design draft to produce accurate mold. The making of the mold must be fine and perfect, because it will determine the shape and outline of the final product.

Second, material preparation and casting

Material preparation: Prepare the required metal raw materials, such as gold bars, gold materials, etc.

Melting metal: The prepared metal raw materials are melted into a liquid state through the melting furnace and other equipment.

Casting: Using wave centrifugal casting machine and other equipment to pour the melted metal into the mold for casting. For chain structure jewelry (such as necklaces, bracelets, etc.), the forging process is generally used; For rings, bracelets, pendants, etc., it may be necessary to make wax trees, which are completed by the lost wax casting process.

Third, preliminary processing

Stripping and cleaning: After the casting is completed, the jewelry is removed from the mold and cleaned to remove impurities and excess materials.

Cutting and finishing: Fine cutting and polishing of parts that need to be cut (such as ring arms, bracelet arms, etc.). These components are prone to stress and wear when worn, so they need to be reinforced and refined.

4. Fine processing and surface treatment

Hammering and filing: Through hammering and filing and other processes to make the jewelry surface more delicate and smooth. This step helps to change the density and hardness of the metal, making it stronger and more durable.

Grinding and polishing: Use sandpaper, polishing machine and other tools to polish and polish the jewelry many times, so that its surface is smooth like a mirror. The polishing process may include steps such as immersion in dilute hydrochloric acid and fine polishing by hand to increase the gloss of the jewelry.

Car flower and pattern making: Make a variety of exquisite patterns and patterns on the surface of jewelry, such as sandblasting, nailing, beading, hand-drawn wire, etc. These patterns and patterns can increase the layer and three-dimensional sense of jewelry, making it more beautiful.

5. Quality inspection and storage

Quality inspection: Strict quality inspection of finished jewelry, including appearance inspection, size measurement, weight verification, etc. Ensure that each piece of jewelry meets design requirements and quality standards.

Warehousing of finished products: the qualified jewelry is weighed, labeled, etc., and sent to the finished product warehouse for sale.

The above is the main process of metal jewelry production. It should be noted that different types and styles of jewelry may differ in the production process, but generally follow the key links of design, casting, processing, surface treatment and quality testing.
